Polio is a serious viral infection that used to be common in the UK and worldwide. It's rare nowadays because it can be prevented with vaccination.

Most people with polio don't have any symptoms and won't know they're infected. But for up to 1 in 100 people, the polio virus causes temporary or permanent Paralysis , which can be life-threatening.

Cases of polio in the UK fell dramatically when routine vaccination was introduced in the mid-1950s.

There hasn't been a case of polio caught in the UK since 1984, although the infection is still found in some parts of the world and there remains a very small risk that it could be brought back to the UK.

There's no cure for polio, so it's important to make sure that you and your children are fully vaccinated against it.
